Continuity and discontinuity in the human use of the north coast of Santa Cruz (Patagonia Argentina) through its radiocarbon record

Peopling time, spatial occupation and demography of Late Pleistocene–Holocene human population from Patagonia

“…Isotopic and zoo-archaeological evidence show that the Late Holocene is characterized by a process of diversification in the subsistence strategies and diet intensification, including the incorporation of small animals and vegetables in Northwest Patagonia and South Cuyo (Gil et al, 2011;Gord on et al, 2016), the incorporation of a large diversity of aquatic resources along the coast (mollusks, fishes and pinnipeds; Zangrando, 2009;Stoessel and Martínez, 2014) and new labour investment in food processing (Stoessel and Martínez, 2014). Particularly, an increase in the consumption of marine resources is simultaneously found between 7500 and 6000 Cal BP in different areas of the Atlantic coast, such as North of Chubut and Santa Cruz provinces, Río Negro and Tierra del Fuego (G omez Otero, 2006;Zangrando, 2009;Favier Dubois and Scartascini, 2012;Zubimendi et al, 2015). It is worth noting that close dates were obtained here for the beginning of the demographic increase in Patagonia.…”

“…The spatial pattern of early human occupations in Patagonia seemed to have occurred almost simultaneously along the Atlantic and Pacific coasts, while the Andean foothills were colonized much later (Borrero, 1994e1995;Miotti and Salemme, 2003;Prates et al, 2013). Previous studies also postulate that human populations were small and stable along Late Pleistocene and Early Holocene, and that an increase in the occupation density only occurred during the Late Holocene, particularly during the last 1000 to 500 years BP (Martínez et al, 2013;Barberena et al, 2015;Zubimendi et al, 2015). It has also been postulated that in some areas of Patagonia population density decreased during the Middle Holocene (Barrientos and Perez, 2005;Neme and Gil, 2008;Salemme and Miotti, 2008).…”

Sites from neighbor areas such as Southern Cuyo and South Pampa were also included because they have been previously discussed together with Patagonian sites in studies that address the peopling of this region.…”

Levantamiento Planimétrico Y Análisis Liquenométrico en El Sitio Campo De Chenques, Costa Norte De Santa Cruz (Patagonia Argentina)

“…Los espacios litorales ubicados al sur de la ría Deseado fueron ocupados recurrentemente en el tiempo (Zubimendi et al 2015), y los recursos marinos se habrían explotado reiteradamente debido a que se presentaban de forma previsible, abundante y segura (principalmente pinnípedos, aves marinas y moluscos). Sin embargo, el consumo de los recursos terrestres no habría sido abandonado, como lo indican los datos isotópicos, los que sugieren la explotación complementaria de recursos terrestres y marinos.…”
